We herein report the first family of Japanese individuals with familial hypobetalipoproteinemia caused by the c.1468C>T mutation in apolipoprotein B (APOB). A 13-year-old boy with extremely low levels of low-density lipoprotein (LDL) cholesterol (24 mg/dL) was referred to our hospital. ⋯ A genetic analysis confirmed that they all had this variant in APOB (c.1468C>T). None of the patients exhibited atherosclerotic cardiovascular diseases or any other complications associated with low LDL cholesterol levels, including fatty liver, neurocognitive disorders, and cerebral hemorrhaging.

Case Reports
Paraneoplastic Cerebellar Degeneration Leading to an Early Diagnosis of Peritoneal Serous Papillary Carcinoma.
A 77-year-old female with a subacute progression of ataxia and serum anti-Yo antibodies was suspected to have paraneoplastic cerebellar degeneration (PCD). An examination of an underlying cancer showed no abnormality in the gynecological organs, but the findings did show a mass in the Douglas fossa. ⋯ PCD was treated with intravenous immunoglobulin (IVIG). For an early diagnosis and treatment, PSPC should be included in the list of malignancies that cause PCD with anti-Yo antibodies.

Case Reports
Nivolumab-induced Thrombotic Thrombocytopenic Purpura in Patients with Gastric Tube Cancer.
Recently, immune checkpoint inhibitors (ICIs) have been used to treat several cancer types. ICIs have been reported to cause a wide variety of immune-related adverse events, including endocrine, neurologic, gastrointestinal, and cutaneous disorders. ⋯ Several previous cases of TTP were thought to have been caused by ICI treatment. We herein report a rare case of TTP that developed after long-term treatment with an ICI (nivolumab) for gastric tube cancer.

Cases of herpes zoster ophthalmicus (HZO) complicated by bilateral ophthalmoplegia are rare, and no cases of bilateral third, fourth, or sixth cranial nerve palsies have been reported. Syndrome of inappropriate antidiuretic hormone secretion (SIADH) is a rare complication of HZO. ⋯ She developed bilateral third, fourth, and sixth cranial nerve palsies and SIADH almost simultaneously during treatment for HZO. The bilateral cranial palsy spontaneously resolved within a few months.

Case Reports
Autopsy of Drug-induced Lung Injury with Atypical Diffuse Alveolar Disorder due to Amiodarone: A Case Report.
Amiodarone, a prominent antiarrhythmic drug, may cause lung injury. We herein report the case of an 87-year-old man who had been taking amiodarone for 5 years and was subsequently referred due to respiratory failure. Chest computed tomography revealed multiple consolidations with air bronchograms in both lungs. ⋯ Autopsy revealed hyaline membrane formation and organic formation with fibrin deposition. Drug-induced lung injury caused by amiodarone was confirmed by autopsy. Caution is therefore required when fibrin deposition in the alveolar spaces is observed in such cases, which are prone to suffer a rapid deterioration.
